Method.
Background technology
At present, plastics are still one of main material of packaging for foodstuff.To reduce environmental pollution, saving petroleum resources, with
And the potential safety hazard that plastics package may bring with direct food contact is reduced, various countries researcher begins attempt to develop all kinds
Plastic-substitute as packaging material for food, predominantly various degradable or edible packing material.Degradable package material
Mainly there are various food wrapper, a films from strings such as timber, bamboo, grass, and various edible packing materials, such as may be used
Feeding habits Vegetable paper, various edible films, mainly with edible natural material, such as polysaccharide, protein, natural plant gum are raw material,
Film with porous network structure or the structure similar to fleece are formed by different molecular interphase interaction.Due to edible
Packaging can with direct food contact, can eat together with packaged food, environmental pollution of also easily degrading, therefore do not result in,
Compared with conventional plastic, there is safety non-toxic, degradable.But majority is edible to be packaged in mechanicalness, hinders wet, oil resistance and resistance
The aspects such as oxygen are remained in larger gap with plastic material, need to be improved in formula composition, preparation method, to reach tool
